Improved boot and shoe stiffener



PATENT OEEICE.

`NATHAN J. SIMONDS, 'OFJ WOBURN, MASSACHUSETTS.

IMPROVED BOOT AND SHOE STIFFENER.

Specification forming part of Letters Patent N0. 105,501, dated July 19, i870.

To all whom it may concern:

Be it known that I, 'NATHAN J. SIMONDS, of Woburn, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Boot and Shoe Stiffenings; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention, suflicient to enable those skilled in the art to which it appertains to practice it.

Y This invention relates to an improvement in the construction or formation of the counterlstiii'enin gs of boots and shoes, as will be hereinafter more fully described.

Figure lis a plan view of the back and interior pieces. Fig. 2 lis a plan view of the front or face piece. Fig. 3 is a transverse section of the stiffening when pasted. Fig. 4 is a similar section', showing the effect of rolling, and Fig. 5 is also a similary section of a stiffenin g as heretofore formed.

Similar letters of reference indicate like parts in the several gures.

In the formation'of 1- stiffenings from thin leather, as heretoforepracticed, the several pieces were cut to the desired form, when they were pasted together, as shown by 1 2 3 4,

Fig. 5, when, .after being dried, the desired beveled Ledge was produced by skiving, as the process is termed,which consists in-beveling the edge by means of a cuttingblade held obliquely to the plane of the stiifening; and

-to effect this process a variety of machines have been devised, n'one of which have satisfactorilyaccomplished the skiving of irregular `or semi-elliptic stiffenings, as shownin Figs.l

1 and 2; besides, the eifect of the dried paste upon the edge of the blade has rendered the process, in all cases, slow, imperfect, and expensive.

In the manufacture of stii'enings as invented by me I cut the back (shown at a) of the full size of the stiffening and of any desired pattern, and upon this I paste the regularly-diminished pieces b c, when the thin cover or face d, of the same size as back a, is pasted upon the whole, as shown in Fig. 3.

When sufficiently dried, the edges are sub-- jected to the action of rollers, as shown at Fig. 4, and, as the edge of each layer is easily attened, a true bevel is readily produced, as shown, the parallel or principal faces beingrolled between parallell ,rollers in the usual manner. Thus a stiffening is produced which has the desired bevel at the edges, and yet has a continuous surface upon both sides.

I do not confine myself to any number of diminished pieces placed between back a and cover cl, as such number may be used as the desired thickness of the stiftening and the thinness'of the stock may render necessary; nor do I claim the employment lof the back a and cover d, broadly, by themselves neither do I claim, broadly, the employment of the diminished pieces b c; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

A stiiiening composed of the back a, one or more diminished pieces, as shown at b c, and the cover d, rolled together or compressed in the manner substantially as described and shown.
